Installation

POWERING UP THE SYSTEM
For the VM102-S with wireless security, remove the shunt from the 2-way header at the
bottom of the security PCB, located in the top left hand corner of the Master fascia
(looking from the rear).
For the VM102-S with wireless security, ensure that the 12V battery is not connected.
For all systems, ensure all the stations and accessories have been installed and correctly
terminated.
Plug the power supply into a power point and turn the power point on.
If the power supply is fitted with its own power switch, turn the switch on.
If the system is fitted with a Master, the radio/clock should illuminate.
For a Room Station only system, press the house talk button at any Room Station,
checking that the green L.E.D. turns on while the button is being pressed.
With a multimeter, measure the DC voltage, at the terminals to which the power supply are
connected.
The measured voltage should be between 13.2 and 14.2 Volts DC.
If the voltage measures low, or the displays and L.E.D.s are not working, turn the power
supply off immediately. Identify and correct the fault before proceeding any further.
If everything appears to be in order, and the system is fitted with a VM102-S Master with
security, connect the battery ensuring that the polarity is correct.
The small lamp on the left side of the termination PCB may glow dimly indicating that the
battery is being charged.
If the lamp glows very brightly, there is a problem that needs to be rectified.
